What protective measures are specified for SCIF walls to protect SCI?

• A. Acoustical protection measures and sound masking systems
• B. Guard dogs and fences
• C. No special protections required
• D. Only standard office walls

Answer: (A)

Protecting SCI through SCIF walls centers on controlling sound and conversations. The walls are constructed with acoustical protection to prevent information from leaking auditorily and may include sound masking systems to obscure speech, making it harder for anyone outside the room to understand what’s being said. This approach directly addresses the risk that classified discussions could be overheard, which is the primary concern for protecting SCI. Perimeter features like guard dogs or fences don’t address acoustic leakage through walls, and claiming no special protections or only standard office walls would be grossly insufficient for SCIF requirements.
